Soil Testing

Soil sampling, GPS mapping & Data management

I saw above me that endless skyway

Why Soil Sample?

~ Gives us information necessary in the decision making process for inputs.~ Allows us to VRT (variable rate) applications, by placing the right inputs on the right acre, at the right time, which:~ Enhances the odds of a greater ROI.

Other Factors:

- Black Sand Granary provides IN-HOUSE labor, testing, and scripts.

- We work for the grower directly.

- YOU own the data. The customer has access to their data at all times, meaning you make the decision of when and where you data goes.

How it works

Step 1: Mapping.

Using a customer-provided boundary we digitize imagery, or import files and download soil type information.

A grid is laid-out, which guides us while sampling.

Step 2: Sampling.

Step 2: Sampling. Soil cores are pulled from each of the points and put into corresponding labeled bags.

Step 3: Lab Work.

The soil samples are shipped to an accredited laboratory for a complete analysis. Our 'typical' test package includes the following: Organic Matter, Phosphorus, Potassium, Magnesium, Calcium and Hydrogen and Soil pH.

Step 4: Analysis.

Converting raw data into a visual representation: results flow through an algorithm, which is proprietary to Black Sand Granary and based off standards of yield removal published by Iowa State University. Software takes this compiled raw data [which is geo-referenced] and plots it within the field boundary. During this process, the data is also interpolated: merging the individual geo-referenced points and corresponding data to the field itself.
